I doubt the ping has anything to do with the framerate. Movement and rendering is pretty much asynchronous to the data sent and received.

Most people who tell me their game is lagging are experiencing graphical lag like very low frame rates. This is caused by a lack of computing power on their machines. You can counter this by getting a bigger CPU, since changing graphic cards may not have much impact (My HD3650 is telling me GPU activity is around 13% while running EQ2).

Server or connection lags usually show in stalling casting bars or npcs not fighting anymore or jumping around. The framerate is unaffected by this. Connection lag does not mean high pings necessarily, for eq2 even several hundreds of ms are fine I guess. Its more the pings' jitter (the variation in ping times) that causes felt lags.
